Don't worry about that comment sternone, that's the nature of forums.
I think its a good subject to raise, and anyone who hasn't flown much in Arrows might well be put off by an accident like this. But if there is anything to learn from the limited amount of information available here is that, excessive deflection of the controls above or around the max maneuvering speed could cause structural damage in almost any aircraft.
That doesn't mean you should be scared of performing steep maneuvers, you may need to perform some to avoid a collision or something. But be aware that there are limitations.
My understanding of the definition of max maneuvering speed is that full control deflection is not permitted.
